API Calling Example
- Use the JavaScript SDK to generate the curl command.
Decompress the SDK. Open demo.html in a browser. The following figure shows the demo page.
- Enter the key and secret of the authorized credential, and specify the method name and request URL. For details, see Obtaining API Calling Information. Example:
// Directly writing AK/SK in code is risky. For security, encrypt your AK/SK and store them in the configuration file or environment variables. // In this example, the AK/SK are stored in environment variables for identity authentication. Before running this example, set environment variables HUAWEICLOUD_SDK_AK and HUAWEICLOUD_SDK_SK.

- Enter query and header parameters in JSON format, and set the request body.
- Click Send request to generate a curl command. Copy the curl command to the CLI to access the API.
//If the subdomain name allocated by the system is used to access the API of HTTPS requests, add -k to the end of -d to ignore the certificate verification. $ curl -X POST "https://c967a237-cd6c-470e-906f-a8655461897e.apigw.exampleRegion.com/app1" -H "X-Sdk-Date: 20180530T115847Z" -H "Authorization: SDK-HMAC-SHA256 Access=071fe245-9cf6-4d75-822d-c29945a1e06a, SignedHeaders=host;x-sdk-date, Signature=9e5314bd156d517******dd3e5765fdde4" -d "" Congratulations, sdk demo is running
The curl command generated using an SDK does not meet the format requirements of Windows. Please run the curl command in Git Bash.
